MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 758,914, dated May 3,1904.

Application filed June 26, 1903. Serial No, 163,180. (No model.)

To all 207mm it may concern:

Be it known that I, WVILLIAM HANSON, a citizen of the United States,residing at (Jalistoga, in the county of Napa and State of California,have invented new and useful Improvements in Mechanical Movements, ofwhich the following is a specification.

My invention has for its object to produce a mechanical movement ordriving power for operating light machinery and performing other workwhere a steady and evenly-running motion is desired; and the inventioncomprises certain novel construction and combination of parts andmechanism, as hereinafter described and afterward pointed out in theclaim at the end of this specification.

The construction and operation of my improved mechanism will beunderstood more clearly by referring to the accompanying drawings, inwhich- Figure 1 is a side elevation of a machine embodying my invention.Fig. 2 is an enlarged view in elevation of the central rocking lever,parts of the lever beingbroken away and its central portion being insection to illustrate its support on the main shaft. Fig. 3 is a topplan view of the mechanism shown in Fig. 1. Fig. 4: is a view, partly inplan and partly in horizontal section, of the parts supported upon oneof the shafts s.

The principal parts of this machine comprise a main driving-shaft a, twowindingdrums b, carrying cords c with heavy weights (1 (l on their ends,and means connecting each drum with an oscillating lever e, through themovements of which the drums are turned in the proper direction to windup the weights. The drums b are connected with the belt-carryingpulleysff in a manner to be described, and these in turn are connectedby the belts g g, the pulleys v o, and other connectinggearing, to belater described, with the main shaft (1, so that the power from bothdescending weights (Z operates to turn the main shaft.

The means for winding up the weights con sist of rocking levers e e,mounted loosely on the shafts s .s and carrying pawls 2', arranged toengage with the ratchet-wheels is, secured to the shafts .s The levers eare connected by rods or links 2? with an oscillating lever it, that ismounted so as to turn freely upon the shaft a. The ratchet-wheels k andthe drums b, from which the weights are suspended, are secured fast totheir respective shafts a, while the pulleys ff are loosely mountedthereupon, but have connection with their shafts and through it with thedrums by means of ratchet-wheels p, secured to the shaft, and pawls 91,carried by the pulleys. It will be seen that if the lever it beoscillated it will operate to rock the levers c e and they in turnthrough the pawls i, which they carry, and the ratchet-wheels Z7,engaged thereby, will operate to turn the shafts a and the drums b indirections to wind up the weights (Z. W'hen this is being done, thepulleys ff" will remain stationary. On the other hand, when the weightsoperate to turn their shafts motion will be communicated from the latterthrough the ratchet-wheels p and the pawls to the pulleys ff. A belt gconnects the pulley f with a pulley 0 on the main shaft a, while thepulley f is connected by a belt g with a pulley a, fast on a short shaft3 that is connected with the shaft (0 by spur-gearing 2 3. This mannerof connecting the second beltpulley instead of placing it directly onthe shaft a is done to reverse the motion of that pulley and apply it tothe shaft a in the proper manner to act in harmony with the otherpulley, and thus cause both pulleys to act on the shaft (4 in the samedirection.

Power is applied to the lever it to rock it on its center by connectingwith the shaft n by means of a crank and a connecting-rod 5, having oneend attached to the lever 7: at a point below its fulcrum and connectedat the opposite end to the crank-pin l. The latter is fixed in a disk 6,fast on the end of the shaft, and a hand-crank 7 is provided in the endshaft for turning it. As thus constructed and arranged the descendingweights act through the drums, pulleys, and belts to rotate the shaft ain the same direction, while the movements of the oscillating lever h,acting through the rocking levers .s' and their pawl-and-ratchet wheelconnections, turn the shafts in the proper direction to wind the cordson the drums.

rocking lever with the shaft upon which it is supported; meansconnecting the oscillating lever with both rocking levers; a drivenshaft, and pulleys and belts connecting the two drumshafts with thelast-named shaft to rotate it in the same" direction.

In testimony whereof I have signed my name in the presence of twosubscribing witnesses.
